The labor intensity of the people is relieved.
Description
Technical field
The present invention relates to art of wheels, particularly relate to a kind of ground-surface wheel construction of unfairness that is used for.
Background technology
At present; The wheel construction majority of all kinds of light manpower hand buggys is common circular wheel, though the road conditions that the dolly of circular common wheel construction can adapt to smooth or ramp are installed, under special road conditions; For example run into step or stair; Need car to jump when upper and lower, just can not normally use, need abandon car and come the object on the transport trolley by the people.
In order to solve the problems of the technologies described above, prior art mainly adopts two kinds of special wheel constructions at present, and a kind of is crawler type, and another kind is a spoke wheel type.The crawler type wheel construction when stair activity and the contact surface of stair very little, only touch with the side edge of stair, therefore, less stable during operation, and the lift angle of existing residential houses stair is bigger, is generally 28 °-34 ° is so its safety performance is desirable not enough.The spoke wheel type wheel construction mainly is made up of axle bed, radiation support tube and scroll wheel etc., and it is a plurality of that radiation support tube operated by rotary motion has, and this spoke wheel type wheel construction has solved the problem little with the stair contact surface; When stair activity; Wheel contacts with the stair plane, and therefore, its safety performance is better than crawler type; But practical effect is desirable not enough, and the subject matter that it exists is: the length of spoke bar can not be adjusted.As everyone knows, there is very big difference in the size of existing stair, and according to the regulation of GB50096-1999 " Code for design of dwelling houses ": the stair step width is not less than 26cm, and step height is not more than 17.5cm.Regulation among the JGJ48-88 " Store Building design regulation ": tread run is not less than 30cm, and step height is not more than 15cm.So the tread run of existing dwelling house and public place stair is 26-30cm, step height is 15-17.5cm.When changing in the scope of step height at 15-17.5cm of stair; If the length of spoke bar is constant; Then load gravity might be between two spoke bar POSs; Also might be positioned at the outside of two spoke bar POSs, promptly be positioned at the land outside of wheel of lower floor ladder, also might with two spoke bars in below the spoke bar coincide.When load gravity between two spoke bar POSs the time, the motion that is suitable for going upstairs, but the motion that is not suitable for going downstairs; When load gravity is positioned at the outside of two spoke bar POSs, the motion that is suitable for going downstairs, but the motion that is not suitable for going upstairs; Therefore, existing spoke wheel type wheel construction is owing to the stair that can not adapt to differing heights, in the process of stair activity; Both be not easy to operation, not laborsaving yet; Exactly because also the length of spoke bar can not be adjusted, even when existing spoke wheel type wheel construction is advanced between the identical stair of step height, its center of gravity can cause bigger jolting because move up and down, and goes thereby dolly can not be stablized.
Summary of the invention
In order to solve the deficiency of above-mentioned technology, the present invention provides a kind of reasonable in design, compact conformation, can be installed on the wheel construction on all kinds of light manpower hand buggys, and this wheel construction can not only be walked level road, especially can easily tackle unfairness ground such as step or stair.
